I am trying to bridge an ethernet network to two different locations. I have the initial bridge setup and EOIP is working great. Now I need to bridge that same ethernet network to a second location. When I try to add ether2 to a second bridge under Bridge / Ports I get ‘Couldn’t add New Bridge Port - device already added as a bridge port’.
Is there any way to share that ether2 between two bridges? Maybe using a VLAN setting or something? Can’t see why I would have to get a third network card just to bridge the same network to a second location…
omg… one interface in two bridges is nonsense!
just add all three interfaces into one bridge
Works great, thanks!
Ну а если так?
этот интерфейс (eth2) подключен к локальному мосту (br1), который собирает всех и выпускает в Сеть через WAN (eth1)
снаружи через PPP туннель просунут EoIP туннель (eoip2), который на той стороне (схожая локалка) подключен к мосту с IPTV.
И вот в своей локалке я делаю такой же мост для IPTV (br2) и втыкаю в него eoip2 и хочу смотреть ТВ оттуда на устройстве, которое подключено к eth2
Мультикаст доходит до br2 - видно, что на нем что-то булькает, по счетчикам то же, что на отправляющей стороне.
И остается мелочь - отправить мультикаст с моста br2 только в eth2, который уже торчит в br1. Как?
Well, if so?
this interface (eth2) is connected to the local bridge (br1), which collects and produces all the Network via the WAN (eth1)
outside through the PPP tunnel is a tunnel EoIP (eoip2), which is on the other side (similar to LAN) connected to the bridge with IPTV.
And here in my LAN I do the same bridge for IPTV (br2) and stick to it eoip2 and want to watch TV from outter LAN on a device that is connected to eth2
Multicast comes to br2 - evident that there is something bubbling on the counters are the same as on the sending side.
And I just need to send the multicast from the bridge br2 only eth2, which is already connected to br1. How?
Sorry for necro-posting
Use Bridge filter to block other multicast ways 
But someone from MT said that in recent versions, there’s IGMP Snooping inside the bridge, so multicast should not be flooded via all bridge ports
